Resin 3.0.x and IIS 6.0

Im having trouble getting IIS to play nice with Resin. It seems that some of my requests that get handled through IIS come back with incomplete responses, and the response header, connection: close.

This only happens when the request page has an abundance of servlet includes, as smaller files get through fine.

If I bypass IIS and access the site via port 8080, all pages come up fine. This leads me to believe there is some "bug" in the isapi filter dll. I've seen multiple people with the same problem as me, but no helpful responses.
